The operation aims to carry out a strategic study on the coordinated development of river sites located on the southern Rhône. This study will constitute the collective spatial planning project on this network of ports and will propose the action plan to be carried out by 2030. The challenges concern the development of multimodality in particular that of inland freight transport, economic development in particular endogenous growth within river sites, optimisation and/or rationalisation of investments and the strengthening of public partnership allowing the sharing of strategic choices.
